For now, however, that whopping $931 billion for fiscal year 2013 will have to do. If our national security budget were its own economy, it would be the 19th largest in the world, roughly the size of Australia’s. Meanwhile, the country with the next largest military budget, China, spends a mere pittance by comparison. The most recent estimate puts China’s military funding at around $136 billion.

Or think of it this way: National security accounts for one quarter of every dollar the federal government is projected to spend in 2013. And if you pull trust funds for programs like Social Security out of the equation, that figure rises to more than one third of every dollar in the projected 2013 federal budget.
